---tab Description---
Stop the Squat. Turn Your Ram 2500 into a Towing Powerhouse.
The 2014-2022 Dodge Ram 2500 is a legendary heavy-duty truck, featuring a unique rear coil-spring suspension designed for a comfortable unladen ride. However, that comfort comes at a cost: when you drop a heavy 5th-wheel RV on the hitch or load up the bed with construction gear, the rear end inevitably sags.
This terrifying "truck squat" causes your front tires to lose steering traction, throws off your braking geometry, and points your headlights blindly into the trees. Worse yet, every pothole results in a bone-jarring bottom-out that damages your suspension and fatigues the driver.
Level Your Load with SPELAB's 7,500-LB Heavy-Duty Air Suspension.Engineered specifically for the Ram 2500 chassis, this premium air helper spring kit acts as a muscular support system for your factory coil springs. Fully adjustable from 0 to 150 PSI, these extreme-duty air bags effortlessly level up to 7,500 pounds of payload.
By restoring your Ram's proper ride height, this kit eliminates trailer sway, body roll, and harsh bottoming out. Get your steering precision back, protect your tires from uneven wear, and experience a smooth, confident towing experience—whether you are pulling a camper on the weekend or hauling supplies to the job site.

Key Benefits

Massive 7,500 LBS Load-Leveling CapacityEngineered to support significantly more weight than standard 5,000-lb aftermarket kits. Effortlessly levels heavy 5th-wheel pin weights, gooseneck trailers, or fully loaded truck beds, restoring a safe and level stance to your HD truck.

Eliminates "Truck Squat" & Trailer SwayAutomatically adjusts your ride height to counteract heavy rear payloads. Keeps your front tires firmly planted on the road for precise steering, safe braking distances, and proper headlight alignment.

Extreme-Duty 6mm Thick RubberConstructed from multi-layer reinforced rubber boasting an impressive 5.9-6.0mm thickness. Provides incredible resistance to road debris, abrasions, and air leaks, ensuring long-lasting reliability in the harshest towing environments.

Fully Adjustable Air Pressure (0-150 PSI)Inflate when heavily loaded and deflate when riding empty. Gives you total control to fine-tune your suspension stiffness for a buttery-smooth ride, regardless of your cargo weight.

Maximum Air Volume for ComfortDesigned intentionally without an internal jounce bumper. Maximizes the internal air volume of the bag, which creates a softer, more dynamic pneumatic cushion to absorb harsh road impacts and reduce driver fatigue.

Ultra-High Burst Pressure SafetyWhile the maximum daily operating pressure is 150 PSI, these bags boast a laboratory-tested burst pressure of 435 PSI (3 MPa). Gives you absolute peace of mind that your air bags won't blow out under sudden impacts, deep potholes, or severe compression.

---tab FAQ---
FAQS
Q: Does this kit increase my Ram 2500's maximum towing capacity (GVWR)?A: No. Air suspension kits are designed to level and support the load, making it safer and more comfortable to carry. You should never exceed the factory-rated maximum Gross Vehicle Weight Rating (GVWR) or payload capacity set by Ram.
Q: Do these bags have an internal jounce bumper?A: No. These air springs are intentionally designed without an internal jounce bumper. This allows for a larger internal air volume, which results in a smoother, less jarring ride quality when towing. Note: You must maintain a minimum of 5 PSI in the bags at all times to prevent them from bottoming out and tearing.
Q: What is the maximum pressure I can run?A: The recommended maximum operating pressure is 150 PSI. While these heavy-duty bags are tested to withstand an extreme burst pressure of 435 PSI (3 MPa), you must strictly adhere to the 150 PSI limit for safe, daily operation.
Q: Will this fit my Ram 3500?A: No. The 2014+ Ram 3500 utilizes a traditional rear leaf-spring suspension, whereas the Ram 2500 utilizes a rear coil-spring suspension. The mounting brackets for this kit are specifically designed for the 2500 coil-spring chassis.
Q: Will this make my truck ride stiff when the bed is empty?A: Not at all! The beauty of adjustable air springs is that you can deflate them to the minimum 5 PSI when you are not hauling. Your truck will ride smoothly on its factory suspension just like it did before the installation.
